Extra ply: When the engine finds the solution, then it should not stop immediately.
The correct move may have come up by chance. The program should at least finish
calculating the current ply depth. This corresponds to the setting Extra ply = 1. If you
want to be sure, you can make the program go one or two plies deeper. This may,
however, greatly extend the processing time.
First position: Allows you to specify from which position the program should start.
Thus, if you have interrupted a session, you can easily continue at a later time.
Previous results: The program keeps a record of the results achieved by each engine
that has run the test. It displays these in a sorted list. This contains the following
results:
The number of positions solved in the allocated maximum time per position.
The average solution time of all the positions that were solved.
The average solution time of all the positions (including those not solved).
This last value, which of course is influenced by the maximum time set, is the most
illuminating. While the program is working you see the current results (how many
positions solved, percentage, average time) in the area just below the status bar at
the top of the board window.
In the displayed ranking list (click “Previous results”), you can delete the results of
individual engines, or all results. You can clip the results (i.e., copy them into the
clipboard and insert them in a spreadsheet program).
The unsolved positions are marked in the database with “medals”. Positions that were
not solved in the current test run are marked with black medals for “Tactical
blunders”. Those not solved by any program, get the “User” medal (blue-green). You
can see the medals in the database list and search for them with the search mask.
This is the best way to get a list of unsolved positions. To load one position after
another, switch to the board window and press F10.
Note: You can define a position as solved if one or more moves are not played. This is
done by annotating them with a "?". For instance if the notation says 1.Ne5? (1.Ng5?)
then the position is solved when neither of these moves is in the main line.

The automatic comparison of the analysis of two different engines has two main uses.
First, it is an excellent way of evaluating the strengths and weaknesses of the
